Notes:
The compressing piston and cylinder of refrigerating compressor frequently come into failuresas anti-wearability for metal material is weak. Engineering ceramics is appreciated by designers thanks toits excellent performances. However, it is difficult to machining material because of high hardness. TheFEA modules for displacement and stress distributions of compressing piston and cylinder under declaredrunning conditions are established based on the theories of elasto-plasticity and aerodynamics, whichreveal the optimal precision conjugation clearance dependence of pressure distributions regularitybetween friction couple. Based on the FEA analytical results, the feasibility of replacing metal materialwith Si3N4 ceramics in the friction couple manufacture is researched. Special clamps have been designedto guarantee the superficial quality as mirror surface and tolerances of form and position, technologicalprocedures are programmed, and with satisfactory machining effect
